2. Safety Instructions
Always adhere to the following safety guidelines to prevent injury and damage to the product or property.
- Professional Installation Recommended: For optimal safety and performance, it is highly recommended that the sink be installed by a qualified professional.
- Handle with Care: The sink is made of a robust material, but can be damaged if dropped or subjected to severe impact during handling or installation.
- Chemicals: Avoid using harsh abrasive cleaners, strong acids, or alkalis, as these can damage the sink's surface. Refer to the maintenance section for cleaning instructions.
- Hot Objects: While the CRISTADUR material is heat-resistant, prolonged exposure to extremely hot objects (e.g., pots directly from the stove) should be avoided to prevent potential thermal shock or discoloration. Use a trivet or heat pad.
- Ventilation: Ensure adequate ventilation during installation, especially if using adhesives or sealants.
- Water Connections: Ensure all water connections are properly sealed to prevent leaks. Check for leaks immediately after installation and periodically thereafter.

4.2. Installation Steps (General)
- Prepare the Countertop: Ensure the countertop cut-out is clean and smooth.
- Install Faucet and Accessories: Mount the faucet and any other accessories (like soap dispensers) into the pre-drilled holes on the sink. These holes can be easily punched out if not already open.
- Apply Sealant: Apply a suitable silicone sealant around the rim of the sink or the edge of the countertop opening, as per manufacturer's instructions for undermount sinks.
- Position the Sink: Carefully lower the sink into the countertop opening, ensuring it is properly aligned.
- Secure the Sink: Use mounting clips or brackets (not included, typically supplied with countertop or by installer) to secure the sink firmly to the underside of the countertop. Tighten evenly.
- Connect Plumbing: Attach the waste fitting, basket strainer, and eccentric control mechanism. Connect the drain to your household plumbing system. Ensure all connections are watertight.
- Test for Leaks: Run water into the sink and check all connections for any leaks.
Important: Always refer to the detailed installation instructions provided with your specific sink model or consult a professional installer.

5. Operation
Your SCHOCK Greenwich N-100L sink is designed for everyday kitchen tasks, offering a spacious basin and durable CRISTADUR material.
- General Use: Use the sink for washing dishes, preparing food, and other standard kitchen activities. The large main basin is suitable for pots and pans.
- Eccentric Control: If your model includes the Comfopush eccentric control, use the push-button mechanism to open and close the drain without reaching into the water.
- CRISTADUR Surface: The smooth, silky surface of the CRISTADUR material is highly resistant to heat, odors, and staining foods. Its water-repellent effect makes cleaning easy.

6. Care and Maintenance
The CRISTADUR material is designed for easy maintenance and high durability. Follow these guidelines to keep your sink looking new.
- Daily Cleaning: For everyday cleaning, use a soft sponge or cloth with warm water and a mild dish soap. Rinse thoroughly with clean water and wipe dry to prevent water spots.
- Stain Removal: For stubborn stains, a non-abrasive liquid cleaner or a diluted solution of vinegar and water can be used. Apply, let sit for a few minutes, then scrub gently and rinse.
- Avoid Harsh Chemicals: Do not use abrasive powders, steel wool, strong acids (e.g., drain cleaners containing sulfuric acid), or strong alkalis (e.g., ammonia-based cleaners) on the sink surface. These can damage the CRISTADUR material.
- Prevent Limescale: In areas with hard water, limescale deposits may form. Regular cleaning helps prevent this. For existing limescale, use a descaling agent specifically designed for kitchen surfaces, following its instructions, or a solution of white vinegar.
- Heat Protection: While heat-resistant, avoid placing extremely hot items directly from the stove or oven onto the sink surface for extended periods. Use a trivet.
7. Troubleshooting
This section addresses common issues you might encounter with your kitchen sink.
| Problem | Possible Cause | Solution |
|---|---|---|
| Water spots/Limescale buildup | Hard water deposits; water not wiped dry. | Wipe sink dry after each use. Use a diluted vinegar solution or commercial descaler for existing buildup. |
| Slow draining | Drain clogged with food particles or grease. | Clear the basket strainer. Use a plunger or a mild drain cleaner (ensure it's safe for plumbing). Avoid pouring grease down the drain. |
| Surface discoloration | Exposure to strong staining agents (e.g., coffee, red wine) for prolonged periods; use of improper cleaners. | Clean spills immediately. Use recommended cleaning agents. For persistent stains, a specialized quartz composite cleaner may be needed. |
| Leaks around connections | Loose plumbing connections; worn seals. | Check and tighten all plumbing connections. Replace worn washers or seals. If unsure, consult a plumber. |
